Problem with ESP8266 Boards

Development Tools IDE 1.x
1

Last year I programmed a couple of ESP-01 boards without problem (IDE 1.8.19). A few months ago I started working with the ESP32. Now I went back to work on an ESP8266 project and I can't find the board definitions. I tried the Boards Manager, and it is not finding any ESP8266 boards.

Can anyone tell me how to get back the ESP8266 boards in the IDE?

Thank you

Open Arduino IDE
File > Preferences
Verify that http://arduino.esp8266.com/stable/package_esp8266com_index.json
is still there.
